' CULTIVATOR.

Application filed December 24., 1917. $eria1 No. 208,679.

To all whom it may concern Be it known that I, CHARLES S. SHARP, acitizen of the United States, residing at Auburn in theoounty of Cayugaand State of New Tork, have invented certain new and useful Improvementsin Cultivators, of which the following is a full, clear, and exactspecification. My invention relates to cultivators, and more especiallyto riding cultivator-s.

One object of'my invention is to provide a means for tilting the frameof the cultivator with respect to the tongue from the operators seat. 1

Another object is to provide means on the main frame to allow verticaland prevent lateral movement of the tongue.

The invention is illustrated on the accompanying sheets of drawings, inwhich- Figure l is a side view of a cultivator showing my improvementsthereon; *ig. 2 is a detail side View showing a portion of the mainframe and tongue having the tilting lever and segmental guide disposedthereon;

Fig. 3 is a plan view of Fig. 2.

The same reference characters designate like parts throughout theseveral views.

This cultivator comprises ground wheels 10 pivotally mounted upon anarched axle 11 and supporting a main frame 12, to which is pivotallyconnected a pole 13, as hereinafter described. A seat 14 is alsoattached to the frame by supports 14. The wheels 10 are each carried bya spindle 16, which is mounted on a bracket 16 journaled upon thedepending portion 17 of the arched axle 11. This bracket also carries aforwardly and upwardly extending lever 18 terminating in a verticalportion 19. To this vertical portion is pivoted a bearing cap 20 toadjustably receive one end of a transversely arranged beam supportingrod 21. Upon this rod are mounted the shovel carrying beams 22, theheads 23 of which are mounted upon the supporting rod.

For guiding the beam support an upwardly extending lug 24, formedintegral with each of the bearing caps 20, is provided, upon which iscarried, parallel with the rod 21, a bar 25. The bar 25 is carried inbearings 26 secured to the main frame 12. Foot steering levers 27 areconnected to the bar 25 by means of the links 27, so that the operatormay cause the bar to shift to either side, thereby turning the wheelsupporting bracket 16 on the arch axle 17 by means of the lever 18. Thewheels 10 carried by the brackets are thus turned to guide thecultivator, and the wheels are kept in parallelism by means of the bar25.

The shovel carrying beams maybe adjusted vertically by means of levers28 and quadrants 28, which are mounted on the frame.

The main frame 12 is pivoted at 29 to the tongue 13. Bolted to andcentrally located on the main frame is a segment and guide member 30.Said guide member comprises two notched segments 31 and 32 integrallyformed, and having an elongated vertical guideway 33 therebetween. Thetongue 13 is pivotally connected to and disposed between the forwardlyconverging bars 3 1 and 35 of the main frame. On the rear end of thetongue is telescopically mounted a plunger 36, having detents 3'7,integrally formed therewith, which engage notches 38 of the segments.The rear end of the tongue 13 fits into the guideway 33, the objectbeing to prevent'lateral movement of the tongue with respect to saidmain frame, and to allow vertical movement of said tongue in theguideway.

T o tilt the main frame a lever 40 is pro vided, which is preferablydisposed centrally of the machine and is within convenient reach of thedriver. This lever carries a depending arm 11, which is pivotallyconnected to the segment 30. Depending links 42 and 13 are alsopivotally connected to the lever 10. Link l2 is pivoted at its lower endto the tongue, while link 43 is pivoted at its lower end to a barrelmember let forming part of the plunger 36. The upper end of link 13 hasa pin 45 passing therethrough, to which is fastened the end of thedetent control link 16, said link having the usual thumb latch control.A stop member 4i? is bolted on the upper side of the tongue, and carriesone end of the detent control spring 48, the other end of which issupported in the barrel member 4A, and acts to keep the detents inconstant engagement with the segment 30 on the main frame.

Varying conditions of the ground to be cultivated, such as variations inthe soil itself, uneven or hilly ground, etc., make it necessary toemploy means for quickly adjusting the position of the cultivator beamsPatented July 13,1920.

in addition to theiisual raising and lowering levers 28; If thecultivator shovels strike 7 of the cultivator beams may be made by thesingle lever 40. This raises or depressesthe forward end ofthecultivator, thereby rais-' ving or lowering thepoint from whichthecultivator beams are suspended, and hence changing the depth ofcultivation.

Wh1le I have shown and described but a single embodiment of. 'myinvention, it

should be understood that the same is capable of modification, andtherefore changes may be made without departing from the f spirit of theinvention or its scope as covered 7 by the appended claims. l

What I claim as my invention and desire V to secureby Letters Patent is:

a 1. In a cultivator, a frame, a tongue vertically-hinged thereto, meansfor raisingand lowering the tongue with respect r to the frame,'asegmentcarried by the frame and 2.. In a cultivator a main frame, atongue, a segment fixed to said mainframe, a lever to operate said armto withdraw said detent to; allow vertical movement of the main framewith respect to said tongue.

3'. In a cultivator, a main frame, a tongue, a segment fixed tosaid mainframe, a lever :pivotally connected to said main frame, a detent carriedby the tongue: in engagement with said segment, anarm pivoted to saiddetent and also'pivotallyconnected to said lever, and means to operatesaid arm to withdraw said detent to allow vertical movement ofithe mainframe with respect to said V tongue to engage said notched segments.-forming a guide for the endof the tongue.

In testimony whereof I aflix mysignature.
